A novel methodology for predicting the high rate mechanical response of polymers from low rate data: Application to (plasticised) poly(vinyl chloride)
Plasticised and unplasticised poly(vinyl chloride) (PVC) are used as engineering materials in many applications where they may be subjected to impact loading leading to high strain rate deformation at a variety of temperatures.

| description | Plasticised and unplasticised poly(vinyl chloride) (PVC) are used as engineering materials in many applications where they may be subjected to impact loading leading to high strain rate deformation at a variety of temperatures. It is therefore necessary to study the mechanical responses of these and similar materials over a range of loading conditions, especially as they exhibit strong rate and temperature dependence, and could include a low temperature brittle transition. In this paper, a model of the mechanical response of a PVC with 20 wt% plasticiser and one with no plasticiser is applied over a wide range of strain rates and strains and shown to have excellent agreement with experiments conducted in a previous study. As it is challenging to obtain high rate data on rubbery materials using conventional apparatus, such as the split-Hopkinson pressure bar (SHPB), an alternative approach is presented based on a novel modelling framework, which uses the time–temperature superposition principle and is fully calibrated using quasi-static experiments at different temperatures. |
